Render pandoc metadata inside the document itself
Write a markdown file, define metadata variable, and use them inside the with double brackets.
---
title: 'Greetings !'
bonjour: 'Hello'
...
## {{ title | upper }}
{{ bonjour }}, {{name}} !
You can also define variable from the command line
with --metadata or --metadata-file :
$ pandoc foo.md --filter=pandoc-jinja --metadata=name:world
<h2 id="title">GREETINGS !</h2>
<p>Hello, world !</p>
-
This filter is slow. In most cases, it is probably more efficient to render the entire document once and for all with jinja and then pass it to pandoc.
-
Jinja conditionals and loops are not supported.
pip install pandoc-jinja
